Quality of Instruction and Mathematical Understanding in Different Cultures of Instruction (Pythagoras)
Funded by the German Research Association (DFG), the German Institute for International Educational Research (DIPF) and Pedagogical University of Zurich jointly conducted the “Quality of Instruction and Mathematical Understanding in Different Cultures of Instruction”. The idea for this study emerged from TIMSS and PISA. These studies delivered important information about strengths and weaknesses of education systems in an international comparison. To reach more differentiated insights into the relevance of concrete instruction for the development of students, assessments of student achievement need to be complemented with micro-genetic studies.
The “Pythagoras” takes this approach by enquiring about contextual-, conditioning and process characteristics of instruction, and assessing their relevance for the students’ development.

FDZ Bildung provides data from the video-based study of lessons, which was part of the overall study and constituted the main focus of research in the project. Data are available in audio (teacher interviews) and AV format (lesson recordings) as well as additional material (anonymized and non-anonymized transcripts, descriptions of teaching units, overviews of teaching units).
For reasons of data protection, audiovisual data and transcripts that have not been anonymized are only accessible after registration and successful verification of rightful access. Descriptions of lesson units and overviews of units as well as anonymous transcripts are openly accessible.
